From 1033f92e15e3f4d5b3a374d254711d66b352b731 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 26 Apr 2016 19:46:33 +0300 Subject: [PATCH] drm/i915: Use cached cdclk value in i915_audio_component_get_cdclk_freq() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit No point in reading the cdclk out from the hardware every single time since we have it cached already. Just return the cached value to the audio driver.
